Based on age and findings, which client would the nurse consider at the highest risk for developing pneumonia?

• A. Client A
• B. Client B
• C. Client C
• D. Client D

Answer: (C)

The main concept here is identifying pneumonia risk by looking at age-related vulnerability and factors that weaken the body's defenses or airway protection. As people age, the immune system and lung defenses become less effective, and clearance of secretions can slow. When age comes with additional risk factors—such as immobility, swallowing difficulties, altered consciousness, or chronic illnesses—the chance of developing pneumonia increases because secretions can pool, aspiration risk rises, and the body’s ability to fight infection is diminished.

The client who is oldest and who also shows findings that indicate impaired airway protection or clearance has the highest risk. That combination—advanced age plus indicators of compromised swallowing, reduced mobility, or other conditions that impair coughing or mucociliary function—raises the likelihood of pneumonia more than younger clients or those without these risk factors.

So, the client identified as the highest risk is the one with the greatest convergence of advanced age and these protective-defense impairments, which makes pneumonia development more likely than for the others.
